"The Meisterburgers... they kind of died off and fell out of power." Really? I always felt that was a bit anti-climactic. Power doesn't just give itself up so easily. I always imagined a sequel, maybe a generation or two after the events of Santa Claus is Coming to Town, in which the Meisterburgers go one step too far in their cruel repression, and they are delivered a fierce beat-down by the Kringles.
This scenario is actually kind of perfect for playing out in a classic fantasy RPG. You've got a beleaguered town in need of saving, a rag-tag group of misfits on the outskirts that is called in to help, and a garrison of low-morale soldiers that may (or may not) obey their evil lord's whims.
Mix that in with the following elements...
- The existence of a shadowy wizard's guild or council (who must have been responsible for "disenchanting" the Winter Warlock),
- The obsequious second-in-command (Grimsby), who may have evolved into more of a Grima Wormtongue type puppet-master, once the original Burgermeister's descendants took over,
- Wild-eyed urchins pushed to the breaking point by pointless sock-washing,
- And don't forget the obvious prevalence of mind-altering substances growing throughout Sombertown that the PCs may stumble into . . .
. . . and you've got yourself one memorable D&D campaign scenario!
